CCX (ranked #1 for singleplayer puzzles) has uploaded a super creative level which plays as a quiz about Clones lore. It's a superb example of how one can create a minigame using the events and triggers available in the editor.

I was impressed at the quality of the questions (and possible answers) as well as the skippable intro tutorial, the customized messages/animation for some wrong answers, the contextual tips/jokes at the upper right for each question, and the score tracking mechanism. I had to play it over and over to see what all the wrong answers do 8-)
